SCALAble SimulaTION  ScalaTion
Papers  Scaladoc  Source Code
Welcome to ScalaTion, the Scalabased system for Simulation, Optimization and Analytics.
This system, coded in Scala, supports multiparadigm simulation modeling including 'tableau', 'event', 'process', 'dynamics', 'dynamics_pde', 'activity' and 'state' oriented models.
Scala is a modern objectoriented, functional programming language that is wellsuited for developing simulation engines. It is in the Java family of languages and can call Java code. The inclusion of advanced and functional programming capabilities, makes the code much more concise than Java. ScalaTion also supports optimization and analytics as they nowadays go handinhand with simulation modeling. Some of the algorithms come in both sequential and parallel versions.
The ScalaTion 1.5 version defines multiple .par subpackages that contain parallel versions of sequential algorithms. Future directions include completing the 'scala3d' and 'physics' packages.
As of version 1.5, ScalaTion consists of 4 subprojects: scalation_mathstat, scalation_database, scalation_modeling and scalation_models

ScalaTion 1.5 is set up to use the Simple Build Tool sbt.
ScalaTion 1.5 uses the following build specification files build.sbt, build.sbt and build.sbt. Source packages are in the src/main/scala directory, class files are in the target/scala2.12/classes directory, and documentation files are in the target/scala2.12/api directory. Data file input, output or analytics are stored in subdirectories of data, while database files are stored in store.
To develop using an IDE:
 Download Scala IDE for Eclipse
 Extract the downloaded .zip/.tar.gz file
 Start eclipse by running the eclipse command or clicking eclipse application from the file manager
 Create and run HelloWorld.scala, see tutorial
